WakeOnLidAction helps prevent your computer from accidently waking up when being transported. It's helpful when you have a MacBook or MacBook Pro which has some sort of "insomnia".

WakeOnLidAction uses a terminal command to change operation mode of the Lid opening action.
The command uses sudo pmset -a lidwake 1 or 0. If you have any questions about pmset try looking in the manpage of this command. (man pmset inside Terminal.app)

Have fun with it!


Mac OS X 10.4 or later

Works great on my macbook pro, but bounces in dock and crashes on launch on my powerbook G4 - the one that actually has the insomnia problem. But that's OK - the description on macupdate was enough to let me write an applescript to do it myself on startup for that old powerbook.

You only need to do this once. When you click on "More Information" on this page you will be guided to the original page for this Application. There you will find more information about pmset and this app. :)
